A particle is located at the vector position r=(4.00i+6.00j)mand a force exerted on it is given by F=(3.00i+2.00j)N.A) What is the torque acting on the particle about the origin?B) Can there be another point about which the torque caused by thisforce on this particle will be in the opposite direction and halfas large in magnitude?C) Can there be more than one of such point?D) Can such a point lie on the y-axis?E) Determine the position vector for such a point.
